CUPERTINO, Calif.--(BUSINESS WIRE)--Feb. 11, 2003

Portal Software, Inc. (Nasdaq:PRSF) and Connexion by Boeing, a business unit of The Boeing Company (NYSE:BA), today announced that Infranet(R), Portal's convergent billing solution, has been selected to serve as the charging and rating system for their groundbreaking new service that provides high-speed Internet connectivity to airline passengers. Portal, a leading provider of billing solutions, will enable Connexion by Boeing to quickly and cost effectively deploy a chargeable version of its broadband service on leading airlines around the globe.

Portal will provide Connexion by Boeing with a fully developed and scalable billing platform that allows the business to easily charge for its Internet services and integrate cleanly with existing business systems. Infranet will authenticate, authorize, and charge passengers in real-time, while also supporting multiple service pricing plans including usage-based pricing and other pricing options being considered by the Boeing business unit.

Connexion by Boeing currently is conducting a commercial service demonstration with Lufthansa, where passengers have real-time access to the Internet, e-mail, firewall-protected corporate intranets and streaming audio and video applications on select trans-Atlantic flights, and will begin a similar demonstration with British Airways next month. Full-scale implementation and rollout of the innovative new service is expected to begin in 2004. Connexion by Boeing also is working with Scandinavian Airlines System (SAS) and Japan Airlines for implementation of the service on their long-haul aircraft.

"Our goal is to have an adaptable billing platform, such as the one provided by Portal, that will make it extremely easy for passengers to sign up for, pay for and use the Connexion by Boeing service," said Joe Shaheen, director of Operational Services. "Through a simplification of the billing process, Connexion by Boeing gains added flexibility that allows us to easily configure our pricing plans, which is a critical part of making our business successful."

Connexion by Boeing required an extremely flexible architecture to adapt to its specialized provisioning and authentication systems that allow passengers to connect to Internet-supported applications during flight. Working together, Connexion by Boeing and Portal were able to configure the billing software to meet this critical business requirement with minimal adjustments.

"As a business traveler who has logged hundreds of thousands of miles, this is the type of service that I've been looking for, especially if it is easy to sign up and pay for," said Glenn Wienkoop, chief operating officer, Portal Software. "The combination of Connexion by Boeing and Portal Software is allowing us to enter a new age of telecommuting."
